787-1664/004-1000 WAGO AC/DC Power Supplies

Wago 787-1664/004-1000 is a protection unit featuring a 4-channel Electronic Circuit Breaker (ECB) module. It allows for the reactivation of all tripped channels via a 15-30Vdc pulse for a minimum of 500ms and enables the switching ON/OFF of any number of channels through a pulse sequence. This unit operates with a supply voltage of 20-28.8Vdc (24Vdc nominal) and utilizes push-in CAGE-CLAMP spring connections. It has a rated current of 3.2A (NEC Class 2 at 28Vdc load) and a rated voltage of 4 x 24Vdc. The design includes active current limitation, status message for each channel via pulse sequence, and compliance with NEC class 2. It does not specify a supply voltage for AC, indicating its DC operation focus. The ambient air temperature for operation ranges from -25°C to +70°C, while for storage, it ranges from -25°C to +85°C. The degree of protection is IP20, and the rated insulation voltage (Ui) is 45 mm. The control voltage for AC includes active current limitation of 3.8A (3.2A at Uo > 25 VDC). It features a mounting mode on a DIN-35 rail, dimensions of H90mm x W45mm x D115.5mm, and a net width of 0.99 inches. The unit can accommodate connection capacities in environments with 5-96% relative humidity (RH), with no condensation permissible. It also includes a 28.8Vdc reverse feed protection and a suppressor diode (33V) for transient suppression on the primary side.
